Somewhere between f8 and f11, I find. I haven't done any real scientific testing to see if this is the case, I just know that shooting with the 50-200 wide open is usually a recipe for soft shots.

Thanks for your opinion. I will try F11. I hopr I can keep the shutter at 1/500 or greater

Photozones lens tests on the original 50-200 showed f11 as the sharpest.

As it happened, I used the DA 50-200 today to shoot some wind surfers.
The used aperture on all was F 7,1 at 1/640 sec.
IMO there is nothing wrong with this lens, I love it.
